  • Patent number: 10252213
    Abstract: Provided is a dehumidification apparatus with good energy efficiency. A moisture absorbing material (polymeric moisture absorbing material 24), which absorbs moisture and swells at a temperature not higher than a predetermined temperature sensitive point, while shrinking and releasing condensed water at a temperature higher than the temperature sensitive point as a result of phase transition, is formed so as to be divided into a plurality of segments which are made apart from each other during dehydration. A rotation motor (21) is used to move the moisture absorbing material (polymeric moisture absorbing material 24) between a moisture absorption region (14a) and a dehydration region (14b). In the dehydration region (14b), the moisture absorbing material (polymeric moisture absorbing material 24) is heated by the heater (25).
